Hi Fred,
following your fix I did this test:
1) I installed the updated theano/gpuarray/dnn.py from
https://github.com/Theano/Theano/pull/5050
<https://www.google.com/url?q=https%3A%2F%2Fgithub.com%2FTheano%2FTheano%2Fpull%2F5050&sa=D&sntz=1&usg=AFQjCNFR8fDmqOsSdghS2mC-7R90hku9Rw>
2) .theanorc is:
[global]
floatX = float16
device = cuda
[cuda]
root = /usr/local/cuda-7.5
[nvcc]
fastmath=True
optimizer =fast_compile
[dnn.conv]
algo_fwd = time_once
algo_bwd_filter = time_once
algo_bwd_data = time_once
3) I use theano.gpuarray.dnn.dnn_conv
out = dnn_conv(img= input,
kerns= self.W,
border_mode='valid',
subsample=(1,1,1),
conv_mode='conv',
direction_hint=None,
workmem=None,
algo=None,
precision=None)
This is the output running a test convnet, that seems quite slow:
